Definition.

4. In this Act, unless the contrary intention appears—

The Minister means the Minister of State for Defence.

Prohibition of building, &c., vessel of war without licence.

5.—(1.) A person shall not, without licence from the Minister—

(a) build any vessel of war, or alter, arm, or equip any ship so as to adapt her for use as a vessel of war;

(b) despatch or deliver, or allow to be despatched or delivered, any ship which has been so built, altered, armed or equipped, either entirely within or partly within the King s Dominions:

Provided that a licence for any such purpose shall not be refused by the Minister unless it appears to the Minister necessary to do so for the purpose of securing the observance of the obligations imposed


by the first-mentioned Treaty, and where a licence is granted subject to conditions, the conditions shall be such only as appear to the Minister to be necessary for that purpose.

(2.) An application for a licence under this section shall be accompanied by such designs and particulars as the Minister specifies.

(3.) The Minister may, by warrant in writing under his hand, empower any person to enter any dockyard, shipyard or other place and to make inquiries respecting any ship being built, altered, armed or equipped therein, with a view to ascertaining whether any ship is being built, altered, armed or equipped in contravention of this Act, and to search the ship.

(4.) If any question arises as to whether a ship is a vessel of war, or whether any alteration, arming, or equipment of a ship is such as to adapt her for use as a vessel of war, the question shall be referred to and determined by the Minister, whose decision shall be final.

Penalties.

6.—(1.) If any person contravenes the foregoing provisions of this Act, or contravenes or fails to comply with any condition subject to which a licence under this Act is granted, he shall be guilty of an offence.

Penalty: Five hundred pounds or imprisonment for two years, or both.

(2.) In addition, the ship in respect of which the offence is committed, and her equipment, shall be liable to forfeiture to the King.

(3.) Where the person guilty of the offence is a company or corporation, every director and manager of the company or corporation shall be guilty of the like offence and liable to the like penalties, unless he proves that the act or omission constituting the offence took place without his knowledge and consent.

(4.) Where an offence against this section has been committed by any person by reason whereof a ship or her equipment has become liable to forfeiture, proceedings may be instituted contemporaneously or not, as may be thought fit, against the offender in any court having jurisdiction of the offence, and against the ship, or ship and equipment, for the forfeiture in a court having jurisdiction in Admiralty; but it shall not be necessary to take proceedings against the offender because proceedings are instituted for the forfeiture, or to take proceedings for the forfeiture because proceedings are taken against the offender.

(5.) Where any ship has become liable to forfeiture under this Act—

(a) any commissioned officer on full pay in the Naval or Military Forces; or

(b) any officer of Customs,

may seize and detain the ship and bring her for adjudication before the High Court or the Supreme Court of a State or any Colonial Court of Admiralty, and the Court may thereupon adjudge the ship with her tackle, apparel and furniture to be forfeited to the King, and make such order in the case as to the Court seems just.


(6.) Any such officer shall not be responsible either civilly or criminally to any person whomsoever in respect of any such seizure or detention, notwithstanding that the ship has not been brought in for adjudication, or if so brought in is declared not liable to forfeiture, if it is shown to the satisfaction of the Court before which any trial relating to the ship or to the seizure or detention thereof is held that there were reasonable grounds for the seizure or detention; but if no such grounds are shown the Court may award costs and damages to any party aggrieved, and make such other order in the premises as the Court thinks just.

(7.) If the Minister is satisfied that there is reasonable ground for believing that a ship has been or is being built, altered, armed or equipped in contravention of this Act, or is about to be despatched or delivered in contravention of this Act, the Minister shall have power to issue a warrant ordering any prescribed officer to seize and search the ship, and to detain the ship, and the officer may seize and search the ship and detain her until the Minister authorizes her release.

(8.) The provisions of sections four hundred and fourteen and four hundred and fifteen of the Navigation Act 1912-1920 shall apply in relation to any ship detained in pursuance of the last preceding subsection in like manner as if the ship were being detained under that Act, and the officer detaining the ship were an official performing a duty under that Act.

(9.) No proceedings shall be instituted in respect of any offence against this Act without the consent of the Minister.

Breaches of Article 1. of Submarine and Poison Gas Treaty.

7. Any person in the service of any Power who violates any of the rules contained in Article I. set forth in the Second Schedule to this Act whether or not that person is under a governmental superior shall be deemed to have violated the laws of war, and shall be liable to trial and punishment as if for an act of piracy, and, if found within the Commonwealth, may be brought to trial before any civil or military tribunal which would have had jurisdiction to deal with the case if the act had been an act of piracy.

Part 4.—Definitions.

For the purposes of the present Treaty, the following expressions are to be understood in the sense defined in this part.

Capital Ship.

A capital ship, in the case of ships hereafter built, is defined as a vessel of war, not an aircraft carrier, whose displacement exceeds 10,000 tons (10,160 metric tons) standard displacement, or which carries a gun with a calibre exceeding 8 inches (203 millimetres).

Aircraft Carrier.

An aircraft carrier is defined as a vessel of war with a displacement in excess of 10,000 tons (10,160 metric tons) standard displacement designed for the specific and exclusive purpose of carrying aircraft. It must be so constructed that aircraft can be launched therefrom and landed thereon, and not designed and constructed for carrying a more powerful armament than that allowed to it under Article IX. or Article X. as the case may be.

Standard Displacement.

The standard displacement of a ship is the displacement of the ship complete, fully manned, engined, and equipped ready for sea, including all armament and ammunition, equipment, outfit, provisions and fresh water for crew, miscellaneous stores and implements of every description that are intended to be carried in war, but without fuel or reserve feed water on board.

The word ton in the present Treaty, except in the expression metric tons, shall be understood to mean the ton of 2,240 pounds (1,016 kilos.).

Vessels now completed shall retain their present ratings of displacement tonnage in accordance with their national system of measurement. However, a Power expressing displacement in metric tons shall be considered for the application of the present Treaty as owning only the equivalent displacement in tons of 2,240. pounds.

A vessel completed hereafter shall be rated at its displacement tonnage when in the standard condition defined herein.

——

THE SECOND SCHEDULE.

Articles of Treaty to Protect Neutrals and Non-Combatants at Sea in Time of War and to Prevent Use in War of Noxious Gases and Chemicals.

Article I.

The Signatory Powers declare that among the rules adopted by civilized nations for the protection of the lives of neutrals and non-combatants at sea in time of war, the following are to be deemed an established part of international law:—

1. A merchant vessel must be ordered to submit to visit and search to determine its character before it can be seized.

A merchant vessel must not be attacked unless it refuse to submit to visit and search after warning, or to proceed as directed after seizure.

A merchant vessel must not be destroyed unless the crew and passengers have been first placed in safety.

2. Belligerent submarines are not under any circumstances exempt from the universal rules above stated; and if a submarine cannot capture a merchant vessel in conformity with these rules the existing law of nations requires it to desist from attack and from seizure and to permit the merchant vessel to proceed unmolested.

Article III.

The Signatory Powers, desiring to insure the enforcement of the humane rules of existing law declared by them with respect to attacks upon and the seizure and destruction of merchant ships, further declare that any person in the service of any Power who shall violate any of those rules, whether or not such person is under orders of a governmental superior, shall be deemed to have violated the laws of war and shall be liable to trial and punishment as if for an act of piracy and may be brought to trial before the civil or military authorities of any Power within the jurisdiction of which he may be found.

Overview

The Treaties of Washington Act 1922 was enacted to enable the implementation of two treaties signed at Washington on behalf of His Majesty and certain other powers. The Act was passed by the Australian Parliament to address the need to enforce the terms of these treaties within Australian jurisdiction. The primary objective of this legislation was to ensure that Australia adhered to the agreed limitations on naval armament and the protection of neutrals and non-combatants at sea, as well as the prohibition of the use of noxious gases and chemicals in warfare. The Act outlines the necessary procedures and penalties for those who might contravene these international agreements, ensuring that Australian laws are aligned with the commitments made in the Washington Treaties.

Scope and Application

The Treaties of Washington Act 1922 applies to the territories under the authority of the Commonwealth and is concerned with the implementation of two treaties signed at Washington in 1922: the Treaty for the Limitation of Naval Armament and the Treaty to Protect Neutrals and Non-Combatants at Sea in Time of War and to Prevent Use in War of Noxious Gases and Chemicals. The Act applies to any person who engages in activities related to the construction, alteration, arming, or equipping of vessels of war, or the despatch or delivery of such ships within the King's Dominions. The Minister, specifically the Minister of State for Defence, has the authority to issue licences for these activities, which must be accompanied by specific designs and particulars as outlined by the Minister. The Act also prohibits the building or altering of vessels in contravention of the treaties and sets out penalties for contravention, including fines, imprisonment, and forfeiture of the ship and its equipment. The Act allows for the seizure and detention of ships suspected of being built, altered, or equipped in contravention of the Act, with specific provisions for the legal proceedings related to such seizures. The Act extends to breaches of the Submarine and Poison Gas Treaty, with provisions for the trial and punishment of those who violate the rules outlined therein. The Act includes detailed specifications for the limitations on naval armament, such as the maximum displacement and gun calibre for various types of ships, and mandates the communication of information regarding new ship construction to the other contracting powers.

Key Provisions

The Treaties of Washington Act 1922 (Act) enacts two treaties signed at Washington in 1922, one concerning the Limitation of Naval Armament (First Schedule) and the other protecting neutrals and non-combatants at sea and prohibiting the use of noxious gases and chemicals in war (Second Schedule). The Act commences on a date fixed by proclamation and applies to all territories under Commonwealth authority. The Minister for Defence is empowered to issue licences for the construction, alteration, arming, or equipping of vessels of war, subject to certain conditions aimed at enforcing the limitations set out in the Treaty of Naval Armament. Licences cannot be refused unless necessary to ensure compliance with the Treaty, and any application must include specified designs and particulars. The Minister can authorise searches of shipyards to ensure compliance and has final authority on determining whether a ship is a vessel of war. Under the Act, any person who contravenes the Act's provisions or fails to comply with licence conditions commits an offence. This includes building, altering, arming, or equipping a vessel of war without a licence or dispatching such a vessel within the King's dominions. The penalties for such offences include a fine of up to £500, imprisonment for up to two years, or both, and the forfeiture of the ship and its equipment to the Crown. If the offender is a company or corporation, its directors and managers are also liable unless they can prove the offence occurred without their knowledge or consent. The Act allows for separate proceedings against the offender and the ship, with forfeiture actions not contingent on criminal proceedings. Officers empowered by the Minister can seize and detain ships believed to be in contravention of the Act, with the burden of proof for reasonable grounds for seizure resting on the officer. Additionally, the Act addresses breaches of Article 1 of the Submarine and Poison Gas Treaty, declaring that any violation of the rules protecting neutrals and non-combatants at sea is a violation of the laws of war, subjecting the violator to trial and punishment as for piracy. Such trials can occur in any civil or military tribunal within the Commonwealth with jurisdiction over piracy cases. The Act also contains detailed limitations on the size and armament of naval vessels, including capital ships, aircraft carriers, and other vessels of war, as well as rules for the replacement of such vessels and the reporting of new constructions to other contracting powers.
